3.0-stable review patch. If anyone has any objections, please let me know.

From: Neil Horman <nhorman@tuxdriver.com>
[ Upstream commit 2f94aabd9f6c925d77aecb3ff020f1cc12ed8f86 ]
Jamie Parsons reported a problem recently, in which the re-initalization of an
association (The duplicate init case), resulted in a loss of receive window
space. He tracked down the root cause to sctp_outq_teardown, which discarded
all the data on an outq during a re-initalization of the corresponding
association, but never reset the outq->outstanding_data field to zero. I wrote,
and he tested this fix, which does a proper full re-initalization of the outq,
fixing this problem, and hopefully future proofing us from simmilar issues down
the road.
